1. Remove Bottom Screws:
   Power off the laptop and unplug the charger. Flip it over and remove all visible Phillips screws from the bottom casing.
2. Pry Open the Case:
   Use a plastic pry tool to gently release the clips around the edges of the palm rest or the bottom cover (depending on your specific E15 sub-model).

   Charge to 100%, leave on charger for 2 hours, then discharge to 5%, and recharge to 100% to sync the system’s power meter.

💡 Pro Tip: While the laptop is open, use a can of compressed air to clean the cooling fan—this helps maintain battery health by keeping the system cool.

Q: How to identify if your battery is an AS16A5K?

A: Check the label on your original battery. It will explicitly list “AS16A5K” or “AS16A8K”. These models are physically identical and interchangeable.

Laptop Maintenance Tips:

1. New battery: For using a new battery, you’d better try a few cycles of discharging to 5%. then charging up to 95%. So that it can be activated completely
2. Overuse: Do not always run out of a battery to 0%, as this would make its usage life.
3. Charging sequence: When charging, first install the battery, then turn on the power. When fully charged, first cut off the power, then pull the power plug.
4. Long-term storage: Please store the unused battery fully charged. (Charge it once a month.) Do not store at low power to prevent reducing the lifespan of a battery
5. Charger: Do not replace the laptop adapter casually. If the original adapter cannot be applied due to malfunction or damage, please replace the models so as not to reduce the service life of the battery due to incompatibility.
